Book Description
Organometallic chemistry is based on the reactions and use of a class of compounds (R-M) that contain a covalent bond between carbon and metal. They are prepared either by direct reaction of the metal with an organic compound or by replacement of a metal from another organometallic substance. This book presents research in this field.

Book Description
[Truncated] This thesis presents work that has been performed in the synthesis of a range of mono and bimetallic organometallic complexes. The electronic and structural characteristics of these complexes have been investigated. Of particular interest is the intramolecular communication between metal centres that can be observed for the bimetallic complexes. Understanding electronic communication is a fundamental concern for the growing field of molecular electronics. The introduction presents a brief background to the field of molecular electronics. This is followed by an overview of mixed valence complexes and the application to the study of electronic communication. The introduction concludes by presenting the ligands that were studied in this thesis, along with a summary of spectroelectrochemistry and theoretical studies as they were applied to the complexes synthesised here. The majority of the complexes studied in this thesis contained a ruthenium ?-alkynyl moiety. Chapter 2 begins with a summary of the properties and synthesis of transition metal ?-alkynyl complexes. The synthesis and characterisation of ruthenium ?-alkynyl complexes of the widely studied ligand 5-ethynyl-2,2'-bipyridine is presented along with a spectroelectrochemical and theoretical investigation of the complexes. Chapter 3 introduces the coordination chemistry of the 2,2'-bipyridine moiety. The complexes synthesised in Chapter 2 were used as metalloligands for the coordination of an additional metal centre to the bipyridyl moiety. The bimetallic complexes were characterised and studied by spectroelectrochemical and theoretical methods. The homobimetallic complexes that were synthesised showed Class II mixed valence behaviour resulting from weak electronic communication. Chapter 4 uses the less studied ligand 4-ethynyl-2,2'-bipyridine to synthesise and characterise a range of mono and bimetallic complexes that were analogous to those synthesised in Chapters 2 and 3. Evaluation of the electronic communication through this ligand by spectroelectrochemical and theoretical methods showed Class II mixed valence behaviour. Comparison of the electronic communication exhibited by complexes in Chapters 3 and 4 showed that there was better electronic communication through the 4-ethynyl-2,2-bipyridine isomer of the ligand.

Book Description
The series Topics in Current Chemistry Collections presents critical reviews from the journal Topics in Current Chemistry organized in topical volumes. The scope of coverage is all areas of chemical science including the interfaces with related disciplines such as biology, medicine and materials science. The goal of each thematic volume is to give the non-specialist reader, whether in academia or industry, a comprehensive insight into an area where new research is emerging which is of interest to a larger scientific audience. Each review within the volume critically surveys one aspect of that topic and places it within the context of the volume as a whole. The most significant developments of the last 5 to 10 years are presented using selected examples to illustrate the principles discussed. The coverage is not intended to be an exhaustive summary of the field or include large quantities of data, but should rather be conceptual, concentrating on the methodological thinking that will allow the non-specialist reader to understand the information presented. Contributions also offer an outlook on potential future developments in the field.

Book Description
In the ten years since the scientific rationale for the design, synthesis and application of inorganic and organometallic polymers (IOPs) was first conceptualised, we have witnessed the first tentative exploration of IOPs as precursors to new materials, with efforts focusing on the design and synthesis of novel ceramic precursors. Developing expertise led to precursor studies combined with the characterisation of the transformation processes that occur when IOPs are converted to ceramic materials. Now at maturity, the science presented in this volume reveals the polymer precursor approach to materials synthesis together with examples of processing ceramic shapes for a range of mechanical properties, the development of sophisticated, noninvasive analytical techniques, and IOP design rationales relying on well-defined processing-property relationships. The production of multifunctional IOPs is described, providing ion conductivity, gas sensing, bioactivity, magnetic properties, etc., combined with processability. The existence of well-defined IOPs and the exquisite control that can be exerted on sol-gel systems now provide access to such a variety of mixed organic-organometallic and/or inorganic hybrid systems that their exploitation is likely to develop into an entirely new field of materials chemistry. Future exciting avenues of research are also being opened up with the advent of buckyballs, Met-Cars, dopable preceramics, rigid-rod organometallics, and molecular tinkertoys.
